"AjTENT OFFfC FLAK-PULLING MACHINE.

Application filed March 6, 1923. Serial No. 623,282.

To all whom it may concern:

Be it known that I, Gnonens MICHOT, a citizen of the Swiss Republic, and residing at Dromara, County Down, Ireland, have 5 invented certain new and useful Improvements Relating to Flax-Pulling Machines, of which the following is a specification.

This invention relates to flax-pulling machines of the type described in British Patent specification No. 153,115, its object belng to simplify the comb-cleaning means of such machines.

The invention broadly consists in providing a pivotally mounted cleaning bar adapted to follow the motion of the comb teeth so that the cleaner remains close to or in contact with the comb teeth and cleans them from end to end as each comb passes the said bar.

In order that the carrying of the invention into efiect may be understood, reference may now be made to the accompanying drawings, in which Figure 1 is a side elevation of the machine;

Figure 2 is a plan view, and

Figure 3 an end view of the machine showing in detail the serrated edges of the cleaning device.

In carrying the invention into effect in one form, I provide a frame, A, made in one nominally rigid structure adapted to support the road-wheel axle, B, and the combcarrying device, hereinafter referred to 1n detail. At the rear end of the machine are curved swinging links or hangers, C, at tached to a shaft, D, mounted within bearings, E, which are fixed in a suitable position on the frame, A, of the machine. The hangers, C, carry at their lower ends cleaning bar, F, preferably having a serrated edge and extending across the comb-carrying part of the machine. The comb pins, G, are carried by a member, H, supported on rigid arms, J, extending from chain belts, K. The latter co-operate with the chain wheels, L L the rear chain wheels, L being driven from the road wheels, M, through suitable gearing, N, and a clutch, O. The chain wheels, L situated at the forward end are in theparticular machine illustrated in the drawings of smaller diameter than the aforesaid chain wheels, L although the diameters of the wheels may, according to circumstances, be in any desired relationship to other. The bearings, P, of the shaft, Q,, carrying the chain wheels, L at the leading end are preferably adjustably fastened to the frame, A, so that the tension of the chain belts, K, may be adjusted. The linear speed of the chain belts, K, relative to the frame, A, is less than the relative speed of advance of the machine, the difference between the said speeds being the speed of advance of the combs, Gr, through the crop. The teeth of the combs are made of rectangular or other suitable section of material and shaped at their ends remote from the comb-carrying brackets in such manner as to facilitate their entry into the standing crop. Provision is made for the prongs of the combs, G, to enter the standing crop at the most suitable angle and this may, for example, be efiected by hinging, as shown at S, or otherwise adjustably fastening the draft ole, S to the frame, A.

The arms, 5, carrying the combs, G, are provided at their upper ends with an element, U, adapted to co-operate with the guide rails, R, and with a roller, V, for contacting with the hangers, C. By providing the roller, V, upon the comb-carrying bracket, J, for contacting with the back of the hangers, C, strains on the combs, G, are relieved and the cleaning bar, F, follows the movements of the combs, G, arising from the motion of the links of the chainbelt around the chain wheels, L,. In operation, each comb, G, carried on its pivot links passes the cleaning bar whose edges traverse the teeth and thus sweep away any adhering material. The hangers, C, are controlled by springs, VV, or the like in such manner that the cleaning bar, F, carried by them is pulled towards the approaching combs, G. The motion of the cleaning bar, F, is preferably limited by a stop, (3,, which ensures correct position of cleaner bar, F, to meet next comb.

The position of the comb-carrying device may be adjusted relatively to the roadwheel axle. This is effected, for example, by attaching a lifting bracket, X, to the bearing, 13,, of the main axle, B, and providing a sliding member, Z, therein suitably fastened to the frame, A, of the machine and an adjusting screw, X working within the lifting bracket, X. The axle bearings, B are retained in position by horn blocks nsane or hearing brackets formed integral with or suitably. fastened to the frame, A. To relieve the whole Weight of the machine from the screw, X a locking pin, X is provided 3 for inserting in the holes, X in the lifting bracket, X, and the'frame, A. I

Having-now described my invention, what I claim as new and desire to secure by Letters Patent is 1. A flax-pulling machine having comb teeth comprising a pivotallymounted cleaning bar adapted to follow the motion of the comb teeth so that theycleaner remains close to or in contact with the comb teeth and cleans them from end toend as each comb passes the said bar. 2. A flax-pulling machine as set forth in the preceding claim, in which a chain belt is employed and in which the said cleaning bar, is preferably serrated, and carried by hangers adapted'toprevent the combs being strained and'to cause the cleaning bar to follow the movement of the comb arising from the motion of the links of the chain-belt.

' In testimony whereof I have signed my name to this specification.

G. MICHOT.
